' Application nle d' March 29, 1923. Serial no. 22,476,

To all whom it vimfz concern:

7 Be it known that I, ALBERT H. JEWELL, a" citizen of the United States,iresiding at Lawrence, in the county of Douglas and 7 State. of Kansas, have invented a certain new and useful Improvement in Insulating Attachments for Oil-Stove Chimneys, of

/ larger proportion ofthe heat units and also intensify the heat which-is produced.

In some chimneys for oil stoveswhich are now in general use there isino insulation whatsoever employed and the heat rays impinging upon the' usual metal wall of the chimney are, in a large measure, absorbed and portions thereof pass through the chimney'wall and are lost, to all practical purposes, for their designed function.

My purpose is to provide a lining for such chimneys as will be adapted to retain the heat unitswithin the chimneyby which'theywill be directed upwardly to the utensil on the stove. A further object is to have this lining reflect the heat rays impinging thereon back into the chimney thereby intensifying the heat'which is conveyed upwardly j for its practical purpose.

A further object is to provide suchalin ing in a construction that can be easily and quickly attached to any of the standard make oil stove chimneys by any person ll accomplish my objectsby means of the details of construction hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings, in which'Fig. 1 shows a planview of an oil stove chimney, my device being in place thereink 7 Fig- 2 shows a sectionalview taken on the line AA in Fig.1; i i Fig. 3shows a sectional vievtaken on the line B-B in Fig. 1; and V Fig; 4 shows a detail jview'iof a-PQ tidn' of the lining being held in place by the shoulder above the door in fachimney- Fig. 5'shows. a detail view. of one ofrthei. v 7
